Ideally, a sub 2" group would be great.
Realistically, 5 shots in a kill-zone would be "acceptable".
Practice, practice, practice...
Try some different ammo, and practice some more...
Rinse and repeat
Im averaging 8" groups with my M&P 9c outside of 15 yards, which is definitely combat effective. I wanted to determine whether my inexperience with compacts outside of conversation range or is it the pistol itself. Ill continue to put rounds downrange at distance to see if this improves.
Actually, shot placement is important to stopping an attacker. I would advise the OP to set a goal and as he improves, set a new goal. One should never be satisfied with their skill level. Don't forget drawing, reloading and tactics.Target sized.
As long as you are keeping them on target, who cares? As long as the handgun is accurate enough so as not to endanger bystanders, who cares? Your goal in a defensive shooting isn't to kill anyone, only to stop agressive action.
Its great that IN has no duty to retreat, because that isn't always practical. That said, there are certain situations where its OK to shoot someone and break contact - you can shoot someone to the ground and then MOVE to a safe distance to make your emergency call. In that kind of a scenario, in the open, you wouldn't need much accuracy at all; virtually any worn out tube would do so long as it functioned.
You don't have to slug it out with the bad guy, and stand over his bullet riddled body, waving your permit card, and play the hero citizen for the cops. Use your discresion and better judgement.
As for fist sized center mass hits ... center mass of what? Center mass is the center of whatever mass is availible - it doesn't denote the torso. Come up with what you think is a practical worst case scenario - half the target obscured by cover, for example, and keep all of your shots on that. Maybe you are around cars and vehicles most of your day, and you percieve a threat in or around vehicles, so you shoot at targets from the sternum up to simulate the target profile of a car jacker, or even from the knees down to simulate shooting under a vehicle. Its up to you and what kind of threat you percieve as to what size your groups need to be.
This.
For a defensive pistol, I'm more concerned with how quickly I can keep all those rounds in a fist-sized circle in the high-center chest area. Bulls-eye shooters may have different standards.
The distance where you would consider retreating would be the better course of action. Actually, IMHO, I think people worry about things like distance and equipment more than they worry about the fundamentals of marksmanship, drawing, tactics, and reloading. If you learn how to shoot a handgun accurately, distances won't worry you. OTOH, if you don't learn marksmanship, you probably won't hit anything beyond touching distance.What's a reasonable maximum distance to practice self-defense with a handgun?
What would you consider an acceptable 5 shot group from a handgun with a sub 4" barrel, in its stock configuration, using factory ammo out to 20 yards? With decent sights and trigger?
